Hmmm, this sounds like your goal is to write an exact 1:1 wrapper of the C
library API (for which there are tools like SWIG&friends). If the library
happens to have a rather unusual, close-to object oriented, high-level C API,
that might work. Otherwise, you might want to try to wrap it in a more Pythonic
look&feel style, that wraps operations and use-cases rather than plain
functions. That should make it easier to hide things like memory allocation and
other C implementation details from users, and will generally increase the
performance of your binding, as it will require less calls for larger operations
in C space.
